IMPROVEMENT IN COTTON-SCRAPING PLOWS.

4Specification forming part of Letters Patent No. 144,509s datedNovember 1l, 1873 application led July 22, 1873.

To all whom it may concern: i

Be it known that I, JAMES M. COBB, of Jackson, in the county of Madisonand in the State of Tennessee, have invented certain new and usefulImprovements in Cotton-Scraping Blows; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof the frame to which the scraper is attached,'and also in the set ofthe handles, all of which will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a side view, and Fig. 2 a rear elevation, of my entirecotton-scraper. Fig. 3 is a perspective view of the frame.

A represents the plow-beam with handles B B. C represents thescraping-blade attached to the frame, and the frame is attached to theunder side at the rear end of the beam A. This frame is constructed of atop bar, D, with two standards, E E, and a foot-piece, G, the standardsbeing curved outward to the left and forward, as shown.

It will be seen that the front standard, E, is bent forward on adownward curve, and that the rear standard, E, at the upper part, isalso bent downward and forward, and then has a short outward anddownward bend to the bottom, so as to contract the length of thefoot-piece between the standards, thereby preventing the clods in therear of the scraper from being thrown over on the plants when thescraper is in operation. The left sides of the standards and the leftedge of the footpiece are flush with each other, while the right-handside of the foot-piece extends considerably to the right of thestandards.

The scraper C is so attached that the left side extends just beyond theleft edge of the ont standard E, to which it is secured, as shown inFig. 2; and the right side of the scraper has a bearing at the bottom'all along the front edge of the foot-piece, and extends just to theright of the right edge of the same. By this manner of forming the frameby bulging outward the standards thereof, an open space is left underthe beam above the scraper, which allows the clods and weeds to fallover and through to prevent thechoking of the plow. The scraper is alsoso at-` tached that a firm bearing. is had on the front standard andfoot-piece. By means of these bearings the scraper-blade will not springor easily become broken. e

It will be observed that the beam is brought into a position almostcentrally over the scraper, and the handles are set in the beam at anangle, and, when the scraper has been placed upon the side of the ridgeto be scraped, they will assume a vertical position, and any down rightforce given by a person upon the handles is naturally distributed alongthe cuttingedge of the scraper.

The forward bolt a, which passes through the beam and secures the framethereto, passes through a slotted opening, b, in this frame, whichadmits of the frame and scraper w being moved either to the right orleft in a lateral direction. The bolts d d, which fasten the scraper Cto the frame, also pass through vertical slotted openings in this frame,which admits of the scraper being raised or lowered, as desired. e

Being aware that a plow having its beam placed over the center of itsplow-blade to secure a central draft is not new, I disclaim such asbeing broadly my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Iatent, is- A The combination of the frame,consisting of the top bar D, outwardly-bent standards E E curveddownward and forward, as described, and the foot-piece G extending Vtothe right of the standards, with the scraper C, the beam A, and thehandles B B, all substantially as set forth.

In testimony that I claim the foregoing I' have hereunto set my h'andthis 2d day of June, 187 3.
